Anal. Biochem. 188, 181-186 (1990). TLC of GPC fractions of NaBH4-labeled oligosaccharides on 3-aminopropyl-bonded silica with acetonitrile - 10 mM triethylamine acetate 3:2. Detection and mapping according to size, anionic charge, and sugar composition. Determination of the distribution of oligosaccharides on bovine submaxillary mucin and rat gastric mucin.
Chromatographia 35, 627-630 (1993). TLC separation of free fatty acids into two fractions, a more mobile group of saturated and monounsaturated fatty acids and a less mobile group containing polyunsaturated fatty acids, on silica with hexane - acetic acid - water 50:2:1. Detection by exposure to iodine vapor, and under UV 254 nm. Determination of polyunsaturated fatty acids by HPLC.
J. Chromatogr. A 803, 235-239 (1998). Modeling of ion-pair HPLC separations by using continuous OPLC. Study of the distribution of several cationic ion-pairing reagents on the layer with mobile phases containing different quaternary ammonium salts, which volumes varied between 4.5 to 67.5 cm3 equivalent to a 1 to 15 bed volume of the given layer. Measurement of the concentration of the reagents after chromatography in 10 samples of the stationary phase used.
Chromatographia 52 (3/4), 175-178 (2000). Investigation of methods for the separation of test mixtures of 10 flavonoids using isocratic RP-HPLC, gradient RP-HPLC, and a coupled isocratic RP-HPLC-NP-TLC system. TLC of the flavonoid fractions separated on RP column, by using 3-step gradient elution with methanol - ethyl acetate, giving a complete separation of the investigated compounds.
J. Chinese Trad. Patent Med. (Zhongchengyao) 25 (10), 798-801 (2004). TLC on silica gel with 1) ethyl acetate - butanone - formic acid - water 10:7:1:1; 2) benzene - acetone 10:1; 3) petroleum ether - ethyl formate - glacial acetic acid 18:1:1. Detection 1) under UV 365 nm, 2) by spraying with 5 % solution of vanillin - acetic acid - perchloric acid and heating at 105 ºC, 3) by spraying with 10 % H2SO4 in ethanol and heating at 105 ºC. Identification by fingerprint techniques. Quantitation of icariine by HPLC.
CBS 97, 2-5 (2006). HPTLC of gangliosides on silica gel with chloroform - methanol - water 24:17:4 and addition of 2 mM CaCl2, after chamber saturation with filter paper for 3 h, over 80 mm, followed by drying for 5 min at room temperature. Detection by dipping in orcin solution (0.3 % (w/v) in 3 M H2SO4) followed by heating at 100 °C for 3 min. Alternative detection of GM3-bands by derivatization with primulin (0.02 % (w/v) in aceton - water 4:1). Quantitative determination by direct IR-MALDI-o-TOF-analysis. The limit of detection for GM3 was about 50 ng/zone.
CBS 102, 2-3 (2009). A semi-automatic interface for hyphenation of TLC with mass spectrometry, which was based on the ChromeXtractor by Luftmann, is introduced. The interface is connected to a HPLC pump and the MS. By means of an extraction piston any target zone can be eluted from a TLC/HPTLC plate directly into the MS. Example: for identification of the zone at hRf 15 in a standard mixture of caffeine, paracetamol, and acetylsalicylic acid the mass spectrum of the zone is recorded. After subtraction of a background spectrum a mass spectrum free from system peaks is obtained, which shows mainly substance signals - here the mass signal m/z 195 [M+H]+ for caffeine.
Rapid Commun. Mass Spectrom. 23, 2711-2723 (2009). HPTLC in combination with matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) was used for the analysis of complex lipid mixtures. For the separation of lipids one-dimensional HPTLC on silica gel aluminum foil was used with a two-phase mobile phase. The combination with MALDI-MS allowed the identification of 70 distinct lipid species and the analysis of even minor lipid classes from only very small volumes of human plasma (50 µL).
